Which two types of organic polymers are made from the same type of monomer?
A
Addition polymers and proteins
B
Addition polymers and polysaccharides
C
Addition polymers and natural rubber
D
Addition polymers and condensation polymers
Verified step by step guidance1
Step 1: Understand the types of polymers mentioned. Addition polymers are formed by the repeated addition of monomers with double bonds (usually alkenes), without the loss of any small molecules.
Step 2: Recognize that condensation polymers are formed by monomers joining together with the loss of small molecules like water, often involving functional groups such as -OH and -COOH.
Step 3: Identify the monomers for natural rubber and addition polymers. Natural rubber is a polymer of isoprene, which is an alkene monomer, similar to the monomers used in addition polymers.
Step 4: Compare this with proteins and polysaccharides, which are condensation polymers made from amino acids and sugars respectively, not from alkene monomers.
Step 5: Conclude that addition polymers and natural rubber are made from the same type of monomer (alkenes), while the others involve different monomer types and polymerization mechanisms.
